Error(s) in loading state_dict for Net: Missing key(s) in state_dict

Hi, thanks for your codes. I trained a checkpoint model named carn_m_180000.pth, but when I testing it by sample.py, I got following error, could you give me some suggestions?

$ python3 carn/sample.py --model=carn_m --ckpt_path=./checkpoint/carn_m/carn_m_180000.pth --sample_dir=./sample/
using this model
{
    "ckpt_path": "./checkpoint/carn_m/carn_m_180000.pth",
    "cuda": false,
    "group": 1,
    "model": "carn_m",
    "sample_dir": "./sample/",
    "scale": 2,
    "shave": 20,
    "test_data_dir": "dataset/DIV2K_valid_LR_bicubic/X2"
}

@wydwww https://github.com/nmhkahn/CARN-pytorch/blob/160a4bc444dd0acfa4bbe93e5f8e45e9cd551c22/carn/sample.py#L96 It missed a parameter scale=cfg.scale. And multi-scale should beFalseif you did not use cfg.multi_scale

@Ji-qing Which parameter is missed? Thanks
